The tragedy is bringing to light the importance of ice safety as winter approaches. Experts say there are a few things you can do to try to prevent this from happening to you or your children. Laura Nichols reports. THERE IS NO SUCH THING AS SAFE ICE. These are words to live by -- according to Mick Klemesrud with Iowa's Department of Natural Resources. He's says you can never bee too careful this time of year... IF YOU SHOW UP TO A LAKE AND YOU DON'T SEE ANY MARKINGS OF ANYBODY OUT BEFORE -- THEN YOU HAVE TO BE CAUTIOUS. Ice conditions vary over different bodies of water -- but as a general rule of thumb -- always make sure there is at least 4 inches of pure ice before you go near it ... IT CAN BE WEAKER IN CERTAIN AREAS SO YOU DON'T EVER TRUST IT. THERE IS ALWAYS A RISK ASSOCIATED WITH GOING OUT WITH IT. It's easy to fall in -- but harder to get out... We submerged a waterproof camera under just a half inch of ice -- and had to crush the ice with a log to get it out... Rescue workers say -- if you fall in -- the key to surviving is not losing your bearings -- you should immediately try to find the hole you fell through... QUICK, FLUTTER, GET UP ON THE ICE, AND THEN ROLL AWAY AS MUCH AS POSSIBLE. In Prescott -- authorities believe one of the brothers went in to help the other -- something experts say is never good... DON'T MAKE THAT FIRST INSTINCT OF RUSH TO THEM BECAUSE EITHER THEY GRAB YOU, YOU CAN'T ASSIST, OR THE ICE FAILS, AND NOW THERE'S TWO VICTIMS. Instead of rushing in to save someone---expe rts say you should scream directions at the victim, throw a rope, and call 9-11. They also advise talking to your kids about the dangers
